[BUG] RequiredField attribute causes condition to disable when it shouldn't

[erdoalParticipant]

When I have [RequiredField] on a BBParameter, and set it to a Blackboard variable that currently resolves to null, this warning appears:

Turns out, I can’t ignore this warning, since on startup an error show up and says that required field is not set, and the whole transition gets permanently disabled (but confusingly, the moving red dots still telegraph that it’s being evaluated).

Hey,

Do you actually set the variable named “Target” in runtime so that it is not NULL before the execution of the condition?

Hi, no, it isn’t set immediately and stays null sometimes. Now it seems I’m using [RequiredField] wrong, for some reason I expected it only to check if the field is linked to something at all, and only throw an error if it’s clearly “NONE”. Sorry.

Hello again,

For your information, the [RequiredField] attribute throws an error if the final resolved parameter value is NULL (or string empty in case of string), regardless of whether or not the parameter is linked to a variable or not linked to variable. “NONE” is also always resulting to a value of NULL as well. Please let me know if this is still an issue for you.

Thanks!
